Often I heard the elders say, "When a person is physically sick, they should go see a doctor, and in the same way, when you're spiritually sick you should go see the elders". So, they compare themselves to doctors...
So, for the sake of it, let's say a JW went to see a doctor and complained about anxiety due to JW meetings and their way of life, and being stressed because the Watchtower asks too much.
Now lets say the doctor would say, the cause of your problems is your religion, stop going and you'll feel better !
So, you go tell the elders that the root of your anxiety is the meetings and field service and all the stress related to the JW religion. So, you tell the elder, didn't you tell us to go see a doctor if we don't feel well?
When I was an active JW, the meetings and field service and giving talks got me nervous. I felt lousy, just knowing I had to give a talk even if it was a month away. I'm sure if I would have went to see a doctor, they would have told me to quit being a JW.
